What Are The Benefits Of Buying Low Emissivity Windows

Posted by mike leigh on April 19th, 2021

A large amount of energy gets lost due to inefficient windows. This can lead to an increase in energy bills.  To avoid heat loss, various types of glass coatings can be used to save money on utility bills. Low-emissivity glass is made with a slim clear coating to block heat. In this article, we will talk more about the advantages of implementing low-emissivity windows.

Window Mart is a leading company that offers replacement windows in Edmonton in Alberta, Saskatchewan, and Ontario. The company offers energy-efficient and superior-quality doors and windows for Canadian climates. Some of their specialization in windows include:

• Awning Windows
• Casement Windows
• Single Slider Windows
• Double Slider Windows
• End-Vent Slider Windows
• Single Hung Windows
• Double Hung Windows
• Fixed Windows
• Picture Windows
• Bay & Bow Windows

Why Should You Buy A Low Emissivity Window?

There can be several benefits of purchasing a low emissivity window at residential or commercial spaces. Let us know about them:

• Blocks Damaging UV Light
• Fails To Filter Natural Light
• Lowers Utility Bills
• Causes a Reduction in Glare
• Provides Superior Level of Insulation Over Glass And Tinted Film

What Is Low E Glass?

Low emissivity glass is known to offer exceptional thermal insulation properties. It has got a specialized coating is applied to the glass that permits the entry of only visible light to a room. In this way, low e-glass blocks harmful infrared and UV rays from making their way into the room.

Besides its protection benefits, the glass also imparts amazing thermal insulation properties wherein it forms a barrier between outside temperature, and inside temperature and prevents energy transfer.

The low e coating of the glass helps maintain the temperature of the interiors in the room. It also reflects the energy waves into the room. In cold-weather season, the glass doesn’t permit the heat of the interiors from going out through windows. In fact, it reflects the sun rays into the room and keeps it warm.

As the heating system of the house doesn’t need to maintain the temperature constantly, it causes a reduction in utility cost. Low e glass is also beneficial in blocking a majority of the infrared radiations.

As it keeps your interiors cooler during summer, it reduces the need for air conditioning to a good extent. Due to all the above benefits, low e glass is found to be highly beneficial in the areas of commercial buildings, glass facades, skyscrapers, etc.

How is the Efficiency Of Low Emissivity Glass determined?

The efficiency of low e glass or low emissivity glass is determined by evaluating the U-Value. This metric is used for the computation of the total amount of heat that has been lost in the window.

The Solar Heat Gain Coefficient of the glass is another factor that is taken into consideration for the computation of the efficiency of low- emissivity windows. This is the solar radiation that gets dispersed via the window. It can be accurately transferred, soaked, or dispensed inward.

Types Of Low Emissivity Glass

Low emissivity glass is categorized into two main types that are as follows:

• Passive Low Emissivity Glass:

This is the type of glass that is assembled using a pyrolytic layer that gets embedded in the glass at the time of development on the assembly line.

• Solar Control Low Emissivity Glass:

This type of glass is made by the application of a thin coating to glass panes present in an insulated chamber. It is more advantageous than the former due to its low emissivity and exemplary solar control.

Conclusion

Looking at the benefits, low e glass is popularly used in the form of glass facades in industrial and commercial structures. Due to the increase in awareness, its application in the residential sector as glass windows has got increased. The initial installation cost of low e glass is high, however, in the long run, it proves to be more affordable in comparison to normal float glass.
